Accessing a web page but storing data locally

We have a requirement to retrieve web pages from a central source such as a .com or .co.uk domain. The problem we have is that the data which would populate the webpage/form needs to be retrieve locally perhaps within a database such as SQL Server.

The data CANNOT be stored centrally online due to data protection.

Technology/Platform not a real issue at this point.

Example
Office has an internal network with an SQL Server/local database. User would access a website where a webpage containing a form would be retrieved and data would be retrieved from the internal SQL Server/local database and integrated and then displayed via a web browser.
